Abstract
A method for transmitting HARQ-ACK information is disclosed. A base station receives a feedback signal transmitted by a terminal when performing a HARQ feedback for a PDSCH; parses TB-level feedback information from the feedback signal according to a number of bits of the TB-level feedback information in the feedback signal; obtains a number of bits of CBG-level feedback information in the feedback signal according to the TB-level feedback information; and parses the CBG-level feedback information from the feedback signal according to the number of bits of the CBG-level feedback information.

A method for transmitting hybrid automatic repeat request acknowledgement information, performed by a base station, comprising:
- receiving a feedback signal sent by a terminal when performing hybrid automatic repeat request (HARQ) feedback for a physical downlink shared channel (PDSCH);
- parsing transport block-level (TB-level) feedback information from the feedback signal according to a number of bits of the TB-level feedback information in the feedback signal, wherein the TB-level feedback information comprises a reception result of the terminal for each TB contained in the PDSCH;
- obtaining a number of bits of code block group-level (CBG-level) feedback information in the feedback signal according to the TB-level feedback information;
- parsing the CBG-level feedback information from the feedback signal according to the number of bits of the CBG-level feedback information, wherein the CBG-level feedback information comprises a reception result of the terminal for each CBG in a TB that fails to be received on the PDSCH;
- wherein, the TB-level feedback information and the CBG-level feedback information are sent by the terminal after independent channel coding.
A method for transmitting hybrid automatic repeat request acknowledgement information, performed by a terminal, comprising:
- receiving downlink data on a physical downlink shared channel (PDSCH);
- generating transport block-level (TB-level) feedback information according to a reception result on the PDSCH, wherein the TB-level feedback information comprises a reception result of the terminal for each TB contained in the PDSCH;
- wherein the TB-level feedback information is used to obtain a number of TBs that the terminal fails to receive on the PDSCH;
- generating code block group-level (CBG-level) feedback information according to the reception result on the PDSCH, wherein the CBG-level feedback information comprises a reception result of the terminal for each CBG in a TB that fails to be received on the PDSCH, and a number of bits of the CBG-level feedback information corresponds to the number of TBs that the terminal fails to receive on the PDSCH;
- independently channel coding the TB-level feedback information and the CBG-level feedback information;
- reporting independently channel-coded TB-level feedback information and CBG-level feedback information to a base station.
A terminal, comprising:
- a processor and a memory configured to store instructions executable by the processor,
- wherein the processor is configured to:
- receive downlink data on a physical downlink shared channel (PDSCH);
- generate transport block-level (TB-level) feedback information according to a reception result on the PDSCH, wherein the TB-level feedback information comprises a reception result of the terminal for each TB contained in the PDSCH;
- wherein the TB-level feedback information is used to obtain a number of TBs that the terminal fails to receive on the PDSCH;
- generate code block group-level (CBG-level) feedback information according to the reception result on the PDSCH, wherein the CBG-level feedback information comprises a reception result of the terminal for each CBG in a TB that fails to be received on the PDSCH, and a number of bits of the CBG-level feedback information corresponds to the number of TBs that the terminal fails to receive on the PDSCH;
- independently channel code the TB-level feedback information and the CBG-level feedback information;
- report independently channel-coded TB-level feedback information and CBG-level feedback information to a base station.
